To an whom-inlay concem:

Be it known that I, Wnmair E. em

TON, a citizen of'the United States, residing atPembroke, in the county of Washington strings to the horn which are tuned to the chromatic scale so that when a tone is made by the talking machine record the string tuned to that tone vibrates in s pathy an also the strings to the armon cs of the tone. Y

The construction and operation of m invention will be described more in detail ereinaiter and ilhistrated in the accompanying.

drawingsinwhich- 1 is a pers tive view of a conventionfi talking 'mac ine with my igprov'ed longi- 'horn secured thereto, Fig. 2, a cent tudinal sectional the innersurface ofthe horn, Fig. 3, a cross I 'ew looking atone side of sectional view, and 4, a detail showing one of the'keys and its-mountings.-

In the; drawings'similar' reference characters indicate corresponding parts throughout the several views.

My improved horn is formed of a number thin ieces of wood, indicated by A, and having t eir edges secured in lo 'tudinal ribs or the horn is shownto have eight sides but this number may be increased or diminished as desired without altering the spirit of my invention.

Secured to the p eces A inside of the horn are cleats C place diagonally on said pieces A so that th line of side of the horn. I p

A, by acting the drawing cleats forms a spiral m- The outer of the A have secured thereto relatively avy ieces ebony or-other suitable having chambers F thereinopenilg"wwards the front of the horn and a hole G connecting each chamber F with the interior of the horn.

' H indicates-keys ha their stems exambers ofthe kind employed in violins and other stringed instrumen s to regulate the tel-on and t e consequent itch of the strings.

I indicate strings avingone endaecui'ed to pegs D and the other end secured'to'keys H, being passed through holes G to the key stems. p

J indicates strips of metal or., other H material secured ad'acentto holes G to space the st'ringslfromt epieces A. v i

' horn for use the strings I In arr m p p are succefiively tuned to. the chromatic scale. When in use the tones produced by the talkrecord causes the sympathetic ing machine -vi ration of the strings I tuned to t e tonic and clearand its harmonics thus prolo the tone reproduction, w 'le .the pieces as sounding boards, strengthen and sweeten the effect produced.

'I claim is- 1. A horn for conveying sound having a multiplicity of flat sides of resonant material, cleats secured to said sides, keys revolubly secured, and strings secured to said cleats and keys and tuned to the chromatic scale, substantially as shown and described.

2. 1A horn for conveying of. longitudinal ribs, thina multi' pieces 0 w secured to said ribs, cleats secured to said pieces of wood, tuning kegs. revolubly secured in the outer e e of t e horn, and strings secured to said '0 eats and keys stantially as shown and described.

In testimony whereof I hereto aflix my signature in the presence of twqwitnesses. *WILLIAM E. LEIGHTON.
